libc++ intentionally provides all the C++11 library functionality that it can,
even when used from C++03 mode. So on the face of it, providing this name in
C++03 mode seems appropriate.
However... the implementation currently used by libc++ **doesn't work** in that
mode
joerg added a comment.
Let me clarify the situation for a moment:
(1) libc++ does try to work in C++03 mode. See the separate implementation of
for pre-C++11. It is also desirable to support. This is completely
beside the question of TR1 support.
(2) The only reason why max_align_t is currently
joerg added a comment.
libc++ generally tries to play nice with C++03 code. It doesn't go out of its
way to break it and keeping it usable helps dealing with a lot of rusty old
code. That's what the patch is all about, not breaking things for no good
reason.

This revision now requires changes to proceed.
the library has never had a C++03 mode, and I am against adding one now. I
want libc++ to move away from C++03, not towards it

max_align_t has been introduced by C++11 and C99. When an older language mode
is explicitly requested, the system headers might not provide. Don't define it
in this case unless other headers ()
